Been awhile since I read Donkin - what I recall is a Spanish illustration of muscovy ducks from an Aztec source hung from a fence or similar that were black and white - thus suggesting domestication resulting in larger areas of white which is apparently a common result in domesticating animals. I thought Columbus brought them back to Europe on his first voyage but Stahl says it was the second. What Columbus brought back isn't completely clear but I find Donkin's argument convincing (given what Columbus wrote) that the muscovy is by far the only reasonable choice. By 1550 or so it was well established as a popular feast bird in France...maybe Italy also IIRC.

Scientific name of the muscovy duck seems to reference Moscow and Cairo - apparently because somebody thought this is where the bird came from. Donkin has other examples - guinea pig and turkey both of which come from South America NOT an African nation or Asia Minor. In my own experience in Brazil a turkey is found on the menu as "Peru"! Why? Its short for "gallinha do Peru" or "Peruvian Chicken"! Poor bird should actually be called "America"! Benjamin Franklin was on to something!
